"An important thing that I want to be honest and bring up is Robin Williams," he wrote on Instagram. "The love and respect I have for this man is boundless. You have my word, we will honour his name and the character of ‘Alan Parrish' will stand alone and be forever immortalized in the world of Jumanji in an earnest and cool way."

In his emotional post, the muscle-bound star went on to write about his first meeting with the funnyman and divulged his hope that Robin's family would be happy with the new movie.

"I have an idea of what to do and I think his family will be proud," he added. "I also think Robin is somewhere lookin' (sic) down and laughing, remembering the first time we met backstage and I (for the first time ever) was a star struck bumbling idiot that couldn't even get my words out...He literally calmed me down w/ (with) that smile and laugh. But that's for another fun story down the road."

The original Jumanji film also starred Kirsten Dunst, Bonnie Hunt and Bradley Pierce as characters who teamed up with Alan to take on the games' perils including man-eating plants, vicious monkeys and a sadistic hunter.

Dwayne explains the new version will see even more unfortunates take on the dangerous game, and promised casting announcements later this week

"Here's another fun part... in the original movie there were three big roles," he explains. "In our new story there's now FIVE. Been so damn cool to see all my actor buddies push their projects aside so hopefully they can come play in our world. Should have cool casting announcements this week. Will keep you posted."

Spider-Man star Tom Holland and comedian Kevin Hart are rumoured to be taking roles in the Jumanji reboot, which is currently scheduled for release in July 2017
